Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic imaging, and in particular to a box and an electronic imaging device in which the box can be installed. Background Art
[0002] Printers are common office equipment. Common printers include inkjet printers and laser printers. Inkjet printers use ink cartridges as consumable containers to spray ink onto paper or other printing media to form text or patterns on the paper. Laser printers use toner cartridges or process cartridges as consumable containers to form text or patterns on paper or other printing media through electronic imaging.
[0003] The existing box for containing toner can be divided into an integrated box and a split box. The split box is provided with a developer box and a drum box that can be detached from each other. The developer roller and the like are installed in the developer box, and the photosensitive drum, the charging roller and the like are installed in the drum box. When the laser printer is working, it is necessary to transfer the developer such as the toner in the developer box to the paper. At this time, the photosensitive drum needs to be in close contact with the developer roller for development. In addition, considering the stability of the developer, when imaging is not required, the developer roller and the photosensitive drum need to be separated. After the photosensitive drum is separated from the developer roller, the photosensitive drum is cleaned by a cleaning brush and the like. Therefore, the existing developer box is provided with a mechanism for separating the developer box from the drum box, and the laser printer is also provided with two sliders, which are separated by the separation mechanism and the sliders to achieve the separation of the developer box and the drum box.
[0004] The separation mechanism on the existing developer box includes two movable parts and a pressure unit. The pressure unit cooperates with the two movable parts so that the two movable parts can swing within a certain angle, thereby cooperating with two sliders to separate the developer box from the drum box. However, since the sliding motion range is very small and the swing angle of the two movable parts is also very small, the installation size of the pressure unit must have very high precision, and the two movable parts must be precisely matched with the pressure unit, so that the developing roller and the photosensitive drum can be evenly pressurized, thereby ensuring the imaging quality.
[0005] Since the developing box and the drum box are easily vibrated during separation and combination, which may affect the image quality, in order to enable the developing roller of the developing box to separate and combine relative to the photosensitive drum and to press the developing roller evenly on the photosensitive drum, the existing pressure unit usually adopts a spring to solve this problem. However, on the one hand, the existing structure has a complex structure, resulting in a high production cost of the developing box. On the other hand, since a movable part and a spring are respectively provided at both ends of the developing box, and each movable part cooperates with a spring, due to the different structures of the two movable parts, the elastic force applied by the two springs is likely to be unbalanced, which may easily cause the movable parts at both ends to be subjected to uneven force and affect the separation and combination of the developing box and the drum box. Summary of the invention
[0006] A first object of the present invention is to provide a box which has a simple structure and low production cost.
[0007] A second object of the present invention is to provide an electronic imaging device having the above-mentioned box.
[0008] To achieve the first purpose of the present invention, the box provided by the present invention includes a box that can be detachably installed in an electronic imaging device, and a first slider is arranged in the electronic imaging device. The box includes a developing frame, and a first end cover and a second end cover are respectively arranged at both ends of the developing frame. The developing roller is supported between the first end cover and the second end cover, and the first movable member is hinged on the first end cover, and the first movable member is provided with a first hooking portion; the first movable member is also provided with a first blocking portion, and the first end cover is provided with a first limiting portion and a second limiting portion; when the first slider moves toward the direction of the first movable member and pushes the first movable member to rotate along the first direction, the first blocking portion can abut against the first limiting portion to limit the rotation angle of the first movable member along the first direction, so that the first hooking portion slides into the first sliding groove of the first slider; the first movable member can abut against the second limiting portion to limit the rotation angle of the first movable member along the second direction, wherein the first direction is opposite to the second direction.
[0009] It can be seen from the above scheme that a first blocking portion is provided on the first movable member, and a first limiting portion and a second limiting portion are provided on the first end cover. The first blocking portion cooperates with the first limiting portion to limit the rotation angle of the first movable member in the first direction, and the second limiting portion can limit the rotation angle of the first movable member in the second direction. In this way, during the process of separating and combining the developing box and the solidifying device, the rotation angle of the first movable member is limited, so that the first hooking portion of the first movable member can be smoothly installed in the first slide groove. Due to the limiting effect of the first blocking portion, there is no need to set a pressure unit such as a spring, so that the structure of the separation structure is very simple, the assembly of the developing box is very convenient, and the production cost of the developing box is reduced.
[0010] A preferred solution is that the electronic imaging device is provided with a driving force output member, and a plane passing through the axis of the developing roller and the axis of the driving force output member constitutes a reference plane; when the first blocking portion abuts against the first limiting portion, the distance between the contact point of the first movable member and the first slider and the reference plane is between 5.5 mm and 6.5 mm; when the first movable member abuts against the second limiting portion, the distance between the contact point of the first movable member and the first slider and the reference plane is between 9.5 mm and 10.5 mm.
[0011] It can be seen that through the limiting action of the first blocking part and the first limiting part, plus the limiting action of the second limiting part, the distance between the first movable part and the reference plane at the two extreme positions is controlled within a specific size range, which can ensure that the first movable part can be smoothly installed in the first slider.
[0012] A further solution is that the first hooking portion is provided with a first guiding inclined surface on one side in the first direction; and / or the first hooking portion is provided with a second guiding inclined surface on one side in the second direction.
[0013] It can be seen that, by providing the guiding inclined surface, the first hooking portion can smoothly slide into the first sliding groove of the first sliding block, or slide out of the first sliding groove.
[0014] A further solution is that a hooking protrusion extending away from the hinge end is provided at the end of the first hooking portion.
[0015] The hooking protrusion can be provided to prevent the first hooking portion from sliding out of the sliding groove of the first sliding block during the process of installing the developing box to the electronic imaging device.
[0016] A further solution is that when the first blocking portion abuts against the first limiting portion, the first movable member is in a first extreme position, and when the first movable member abuts against the second limiting portion, the first movable member is in a second extreme position; the rotation angle of the first movable member when rotating from the first extreme position to the second extreme position is between 15° and 20°.
[0017] It can be seen that the rotation angle of the first movable member is limited by the limiting action of the first limiting portion and the second limiting portion, thereby preventing the first movable member from rotating too much and affecting the cooperation between the first movable member and the first slider.
[0018] A further solution is that the first movable part has a hinged end and a connecting portion, and the connecting portion is connected between the hinged end and the first hooking portion; along the extension direction of the connecting portion, the distance between the rotation center of the hinged end and the distal end of the first hooking portion is between 18 mm and 20 mm.
[0019] A further solution is that a second slider is also provided in the electronic imaging device; a second movable part is hinged on the second end cover, and the second movable part is provided with a second hooking portion; the second movable part is also provided with a second blocking portion, and a third limiting portion and a fourth limiting portion are provided on the second end cover; when the second slider moves toward the direction of the second movable part and pushes the second movable part to rotate along the first direction, the second blocking portion can abut against the third limiting portion to limit the rotation angle of the second movable part along the first direction, so that the second hooking portion slides into the second sliding groove of the second slider; the second movable part can abut against the fourth limiting portion to limit the rotation angle of the second movable part along the second direction.
[0020] It can be seen that the second movable member is provided with a second blocking portion, and the third limiting portion and the fourth limiting portion are provided on the second end cover. The second blocking portion cooperates with the third limiting portion to limit the rotation angle of the second movable member in the first direction, and the fourth limiting portion can limit the rotation angle of the second movable member in the second direction. In this way, in the process of separating and combining the developing box and the solidifying device, the rotation angle of the second movable member is limited, so that the second hooking portion of the second movable member can be smoothly installed in the second slide groove. Due to the limiting effect of the second blocking portion, there is no need to set a pressure unit such as a spring, so that the structure of the separation structure is very simple, the assembly of the developing box is very convenient, and the production cost of the developing box is reduced.
[0021] Since the two movable parts at both ends of the developing box do not need to cooperate with the springs, but the blocking parts and limiting parts of the same specifications respectively cooperate to achieve the limitation of the two movable parts, the two movable parts can smoothly cooperate with the two sliders, and the problem of uneven force at both ends of the developing box due to the use of two springs can be avoided, thereby improving the imaging quality.
[0022] A further solution is that the electronic imaging device is provided with a driving force output member, and a plane passing through the axis of the developing roller and the axis of the driving force output member constitutes a reference plane; when the second blocking portion abuts against the third limiting portion, the distance between the contact point of the second movable member and the second slider and the reference plane is between 8.5 mm and 9.5 mm; when the second movable member abuts against the fourth limiting portion, the distance between the contact point of the second movable member and the second slider and the reference plane is between 10.5 mm and 12 mm.
[0023] It can be seen that through the limiting action of the second blocking part and the second limiting part, plus the limiting action of the second limiting part, the distance between the second movable part and the reference plane at the two extreme positions is controlled within a specific size range, which can ensure that the second movable part can be smoothly installed in the second slider.
[0024] A further solution is that when the second blocking portion abuts against the third limiting portion, the second movable member is in the third extreme position, and when the second movable member abuts against the fourth limiting portion, the second movable member is in the fourth extreme position; the rotation angle of the second movable member when rotating from the third extreme position to the fourth extreme position is between 7° and 12°.
[0025] It can be seen that the rotation angle of the second movable member is limited by the limiting action of the third limiting portion and the fourth limiting portion, thereby preventing the second movable member from rotating too much and affecting the cooperation between the second movable member and the second slider.
[0026] To achieve the second objective mentioned above, the electronic imaging device provided by the present invention comprises a housing, a box installation position is provided in the housing, and the box installation position is detachably installed with the box mentioned above.

[0066] When the first blocking portion 210 abuts against the first limiting portion 122, the first movable member 200 is in the first limit position. Fig.10 As shown. The electronic imaging device is provided with a driving force output member arranged in parallel with the developing roller.

[0067] During the separation and combination of the developing cartridge and the drum cartridge, the first movable member 200 can rotate around the hinge shaft 121. When the first movable member 200 rotates along the second direction, as shown in FIG. Fig.11As shown in the direction of the arrow, the first movable member 200 can abut against the second limiting member 123. At this time, the first movable member 200 is in the second limit position. Fig.11 It can be seen that the connecting portion 202 of the first movable member 200 abuts against the second limiting member 123, thereby limiting the rotation angle of the first movable member 200 in the second direction. Figure 5 and Fig.11 It can be seen that the first direction and the second direction are opposite rotation directions, for example, the first direction is a counterclockwise direction, and the second direction is a clockwise direction.
[0068] See also Fig.12 When the first movable member 200 is in the second limit position, the distance D4 between the contact point 231 of the first movable member 200 and the first slider and the reference plane 400 is between 9.5 mm and 10.5 mm, preferably 10 mm.

In addition, a third limiting portion 132 and a fourth limiting portion 133 are also arranged on the side of the second end cover 130 facing the first end cover 120, wherein the third limiting portion 132 is a rib formed on the second end cover 130, and the third limiting portion 132 protrudes from the surface of the second end cover 130 toward the direction of the first end cover 120, and the fourth limiting portion 133 is arranged at the edge of the second end cover 130, and also protrudes from the surface of the second end cover 130 toward the direction of the first end cover 120.
[0070] See also Fig.17 and Fig.18 The second movable member 300 has a hinge end 301, and the hinge end 301 has a through hole. The hinge end 301 can be sleeved on the hinge shaft 131 so that the second movable member 300 rotates relative to the hinge shaft 131. The second movable member 300 is also provided with a connecting portion 302 and a second hooking portion 303, wherein the connecting portion 302 is connected between the hinge end 301 and the second hooking portion 303, and the second hooking portion 303 is hook-shaped, and the side facing away from the hook-shaped opening is a plane 305, and an inclined surface 306 is formed between the plane 305 and the connecting portion 302.
[0071] The second movable member 300 is further provided with a second blocking portion 310, wherein the second blocking portion 310 is connected to the hinge end 301, the second blocking portion 310 is bent, and a contact surface 311 is formed at the end thereof, and the second blocking portion 310 can contact the third limiting portion 132, such as Fig.19 As shown, the abutting surface 311 abuts against the third limiting portion 132. When the second movable member 300 rotates along the first direction, as shown in FIG. Fig.19 If the second movable member 300 rotates in the direction indicated by the arrow, the cooperation between the second blocking portion 310 and the third limiting portion 132 can limit the rotation angle of the second movable member 300 in the first direction.
[0072] When the second blocking portion 310 abuts against the third limiting portion 132, the second movable member 300 is in the third limit position. Fig.19 When the second movable member 300 is in the first limit position, the distance D5 between the contact point 331 between the second movable member 300 and the second slider and the reference plane 400 is between 8.5 mm and 9.5 mm, preferably 9 mm. In addition, when the second movable member 300 is in the third limit position, the contact point 331 between the second movable member 300 and the second slider is located on the plane 305. At this time, the angle γ between the plane 305 and the reference plane 400 is between 20° and 24°, preferably 22°.
[0073] During the separation and combination of the developing cartridge and the drum cartridge, the second movable member 300 can rotate around the hinge shaft 131. When the second movable member 300 rotates along the second direction, as shown in FIG. Fig. 20 As shown in the direction of the arrow, the second movable member 300 can abut against the fourth limiting member 133. At this time, the second movable member 300 is in the fourth limit position. Fig.21 and Fig. 22 It can be seen that the inclined surface 306 of the second movable member 300 is on the fourth limiting member 133 , thereby limiting the rotation angle of the second movable member 300 in the second direction.
[0074] See also Fig. 22 When the second movable member 300 is in the fourth limit position, the distance D6 between the contact point 332 of the second movable member 300 and the second slider and the reference plane 400 is between 10.5 mm and 12 mm, preferably 11.1 mm. When the second movable member 300 is in the fourth limit position, the contact point 332 of the second movable member 300 and the second slider is located on the plane 305. At this time, the angle δ between the plane 305 and the reference plane 400 is between 29° and 33°, preferably 31°. Therefore, the rotation angle of the second movable member 300 when rotating from the third limit position to the fourth limit position is between 7° and 12°.
[0075] Combine the following Figure 23 to Figure 33The process of the developer box engaging with the first slider 160 and the second slider 170 is described. The electronic imaging device is provided with the first slider 160 and the second slider 170, wherein the first slider 160 is used to cooperate with the first movable member 200, and the second slider 170 is used to cooperate with the second movable member 300. The first slider 160 has a contact portion 161 and is formed with a first slide groove 162; the second slider 170 has a contact portion 171 and is formed with a second slide groove 172.
[0076] See also Fig.23 and Fig.24 In the first stage of assembling the developing box 100, the developing box 100 is not in contact with the first slider 160 and the second slider 170. At this time, there is a certain distance between the first movable member 200 and the first slider 160, and there is also a certain distance between the second movable member 300 and the second slider 170. The first movable member 200 and the second movable member 300 can both rotate freely within a limited angle range.
[0077] See also Fig.25 When the developing box 100 starts to contact with the first slider 160 and the second slider 170, the cooperation between the developing box 100 and the two sliders is in the second stage, such as Fig.26 As shown, the back of the first hooking portion 203 of the first movable member 200 contacts the contact portion 161 of the first slider 160. At this time, the first blocking portion 210 of the first movable member 200 abuts against the first limiting member 122, so that the first movable member 200 cannot continue to rotate in the first direction. Fig. 27 As shown, the back side of the second hooking portion 303 of the second movable member 300 contacts the contact portion 171 of the second slider 170, and the second blocking portion 310 of the second movable member 300 abuts against the third limiting member 132, so that the second movable member 300 cannot continue to rotate along the first direction.
[0078] Then, if Fig.28 As shown, the developing box 100 continues to move toward the first slider 160 and the second slider 170, and the cooperation between the developing box 100 and the two sliders is in the third stage. Fig.29 However, since the first blocking portion 210 of the first movable member 200 abuts against the first limiting member 122, the first movable member 200 cannot continue to rotate in the first direction. As the first movable member 160 continues to move toward the developing box 100, the first hooking portion 203 passes over the contact portion 161 and extends into the first sliding groove 162. Fig.30 As shown, the second hooking portion 303 of the second movable member 300 also passes over the contact portion 171 of the second sliding block 170 and extends into the second sliding groove 172 .
[0079] Finally, the first hooking portion 203 of the first movable member 200 is limited in the first sliding groove 162 of the first slider 160, and the second hooking portion 303 of the second movable member 300 is limited in the second sliding groove 172 of the second slider 170. Fig.31 As shown in FIG. 1 , the cooperation between the developing box 100 and the two sliders is in the fourth stage. Fig.32 After the first hooking portion 203 of the first movable member 200 slides into the first slide groove 162, it abuts against the inner wall of the first slide groove 162 in both the first direction and the second direction, thereby limiting the first movable member 200. In addition, due to the limiting effect of the second limiting portion 123 on the first movable member 200, the rotation angle of the first movable member 200 in the second direction is limited, and the first movable member 200 will not slide out of the first slide groove 162 due to the excessive rotation angle of the first movable member 200 in the second direction. In addition, since the first hooking portion 203 is provided with a hooking protrusion 208, the hooking protrusion 208 can abut against the inner wall of the first slide groove 162, which can effectively prevent the first hooking portion 203 from sliding out of the first slide groove 162.
[0080] See also Fig.33 After the second hooking portion 303 of the second movable member 300 slides into the second slide groove 172, it abuts against the inner wall of the second slide groove 172 in both the first direction and the second direction, thereby limiting the second movable member 300. In addition, due to the limiting effect of the fourth limiting portion 133 on the second movable member 300, the rotation angle of the second movable member 300 in the second direction is limited, and the second movable member 300 will not slide out of the second slide groove 172 due to excessive rotation angle in the second direction.
[0081] Since in the developing box 100 of the present invention, the first movable part 200 and the second movable part 300 are respectively provided with the first blocking portion 210 and the second blocking portion 310, by respectively providing a plurality of limiting portions on the first end cover 120 and the second end cover 130, the first movable part 200 will not slide in the first sliding groove 162 after sliding into the first sliding groove 162, and the second movable part 300 will not slide in the second sliding groove 172 after sliding into the second sliding groove 172, thereby realizing the positioning of the developing box 100 and the first slider 160 and the second slider 170.
[0082] In this way, the present invention does not need to set a spring in the developing box 100 or the electronic imaging device, and the first movable member 200 and the second movable member 300 are all one-piece parts, such as one-piece injection molding, and do not need to be assembled. The structure is simple, and the assembly process of the developing box 100 is simplified, which can reduce the production cost of the developing box 100 and improve the assembly efficiency of the developing box 100. In addition, since the developing box 100 does not need to be provided with a spring, the problem of affecting the imaging quality due to the inconsistent elastic force of the springs at both ends of the developing box 100 will not occur.
[0083] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
